I once had a friend with a severe irrational fear! Just the mention that there were real numbers that could not be expressed as a ratio of whole numbers made him shake. I showed him Pi calculated to the hundredth decimal place and he passed out dead away. The last time I saw him was when someone told him that the square root of -1 was part of the equation describing radio waves and then held up a transistor radio to taunt him. He ran out screaming. I hear he does the voice of the Counting Vampire on Sesame Street... so much in love with whole numbers and their ratios, he really believed in a Rational World!_________________Penny Awful Press
